Intraoral Scans Alignment in Single Edentulous Arch Cases

Using intraoral scans for removable denture fabrication requires proper alignment according to maxillo-mandibular relationships. The presented technique combines intraoral and extraoral scanning of the occlusion rim to obtain intraoral scan alignment and the transfer of all information for tooth arrangement to the digital workflow. The technique was developed for single edentulous arch cases and is particularly indicated for the edentulous mandible; nonetheless, it can also be used for the maxilla if a full-size occlusion rim is required for optimal stability.
